Clean Air act - 608
EPA - Environmental Protection Agency .......Answer.........to
minimize the quantity of refrigerants released to the
atmosphere, and to maximize the recovery and recycling of
refrigerants during the servicing and disposal of mobile and
stationary air conditioning and refrigeration equipment.
ozone .......Answer.........a layer in the earth's stratosphere at an
altitude of about 6.2 miles (10 km) containing a high
concentration of ozone, which absorbs most of the ultraviolet
radiation reaching the earth from the sun.
,age 2 of 28
chlorine .......Answer.........the chemical element of atomic number
17, a toxic, irritant, pale green gas.
freon .......Answer.........a gas at room temperature and a liquid
when cooled or compressed. Freon gas is colorless, non-
flammable and relatively odorless. Some Freon gases have an
ether-like odor.
Four categories of certification .......Answer.........1. Type I - small
appliances
2. Type II - high pressure appliances
3. Type III - low pressure appliances
4. Universal - both low & high pressure and small appliances
refrigeration .......Answer.........movement of heat from an area
where it is not wanted to an area where it is less objectionable
, age 3 of 28
vapor/compression refrigeration cycle .......Answer.........may be
defined as lowering the temperature of an enclosed space by
removing heat from that space and transferring it elsewhere. A
device that performs this function may also be called an air
conditioner, refrigerator, air source heat pump, geothermal heat
pump or chiller (heat pump).
gauge manifold set .......Answer.........allows the HVAC technician
to check central air conditioning unit operating pressures,
transfer Ac refrigerant, pressure test system, purge the system
with nitrogen, and perform other necessary tasks.
pressure/vacuum .......Answer.........pressure as defines as the
force per unit area, most often described as pounds per square
inch (U.S.)
